Amateur Radio Afloat and Portable

The Raspberry Pi Project – Part 2

Hi Again Everyone, Today the rest of the parts to build my Portable Station Computer arrived No, Im not doing an unboxing video... I ordered these parts from RS Components Adafruit Ultimate GPS Hat Provides GPS and PPS time source, with battery backed up time....

The Raspberry Pi Project

Hey all Ive been thinking about my portable computing set up again, and I've come back to the Raspberry Pi. So what Im planning to do is (finally!) produce a series of blog posts about setting this up as the best amateur radio portable computer that I can, its going...

Portable Operation

Over the past couple of months Ive been putting together a couple of portable stations, this one uses a hand truck/sack truck, not only does this enable me to move it about quite easily it also acts as the ground plane for the vertical antenna which is held up with...

Portable on the River Hamble

I spent a few hours completing some work on my portable station this afternoon, and was very pleased with the results. I had QSOs on 20m SSB with stations in Lapland, Serbia, Bosnia and in Iceland using 25watts into my vertical 1/4 wave wire and artificial ground,...

Let’s go fly a kite

it was windy enough today to try out my Chameleon Emcomm II on the river. Unfortunately too windy and gusts so the antenna wire kept dipping in the water. But I got the kite up in the air and could hear some stations on 20m so it’s working fine. i have also finished...

Power for the Raspberry Pi and Adafruit GPS hat

Instead of using a 12volt to USB power port which sometimes cause noise on lower HF bands I thought I would give this a try. its a UBEC DC-DC coverter which takes a 5.5 to 26volt input and gives us a steady 5volt supply and it supposed to have limited EM interference....

Adafruit GPS hat, with Real Time Clock for Raspberry Pi

I added the Adafruit GPS hat to my Raspberry Pi 3B+ today. As well as a GPS it has a real time clock, which should help the time accuracy of the Pi. My first problem was that I had to solder the GPIO connector on. Don’t look to close at the pic, it’s not very good...

Setting the Raspberry Pi System Time using a GPS

Having an accurate time source is important for some digital modes, and normally not a problem when your Raspberry Pi is connected to the internet. But what about when you are at sea or in the middle of the forest or anywhere else with no internet connection? I tried...

All in one Portable Modular Station

Last week I spent some time reading the posts in the Facebook group “RealHFMobile”, There are some members of the group who are having great success using Artificial Gound also known as Ground Tuning Units “GTU” attached to a trolly along with a whip antenna so that...
